They will tell you, for example, that they find their job fascinating, or that they love meeting people in the course of their work, or that it offers many little satisfactions in a working day, offsetting the many little frustrations. And so on.
Samuel Johnson wondered angrily how anybody could say they enjoyed something (work) which they only started each day reluctantly and left off each day with relief. It is a fair point, but enjoy it we often do. In part this is because of those inherent satisfactions – psychologist Mihaly Csikszentmihalyi talks of the concept of ‘flow’ where you get so lost in your occupation that you become unaware of the passage of time or of you bodily needs: you forget to eat lunch, forget to go home, forget to sleep.
Most of us do not experience flow on a daily basis, but in other ways, work can be good for us. It takes us out of the house, makes us interact with people, feeds into our sense of self-esteem (on a good day) and so on. These are all recognised to correlate with our long term health.
Correlation is not causation, of course. Incessant work will kill you, spiritually if not physically. But the sharp separation of work-life from life-life, where work happens in your workplace and life happens everywhere else, is a function of industrialisation. Work, in other contexts, bleeds into life. It is just one more thing that you do. It may be that we are experiencing, not a take-over of our lives by our work, but the re-establishment of more natural patterns of work and non-work. To go to work is not or will no longer be a question of going from a place that you like to a place that you hate.
